I noticed 2 things.  One is quite annoying.
1) sunlance:
Nov 19 19:09:49 sparq kernel: eth0: Carrier Lost, trying AUI
Nov 19 19:09:52 sparq kernel: eth0: Carrier Lost, trying TPE 

This has been going on for some time since it has been up.  But I think
something oopsed to cause this

2) the oops.  It oopsed 3 times.  I have attached the oops.

-- 
 Lab tests show that use of micro$oft causes cancer in lab animals

[wakko@sparq:/home/wakko] ksymoops < kernel 
ksymoops 2.3.4 on sparc 2.4.0-test10.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.0-test10/ (default)
     -m /boot/System.map-2.4.0-test10 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.
